RICH Decisions is a Java-applet and therefore requires a Java-enabled
browser. For security reasons RICH Decisions can only save models on the
server. To get your own private working directory you have to register.

Note that Java-technology is highly dependent of the
web-browser used. Therefore, if the software doesn't work properly, please try
another browser/version. RICH works properly at least with the following
browsers:
Internet Explorer 6.0.2800.1106 SP1 Win2000
Netscape Navigator 6.1 with Java-Plugin 1.3.1 Win2000
